System, comprising an inner container and an outer container

A system, comprising an inner container (2) and an outer container (1), wherein:

• the inner container (2) comprises a first interior (4), which is surrounded by a first wall, and a circumferential collar (8), which protrudes outward away from the first wall;
• the outer container (1) comprises a second interior (3), which is surrounded by a second wall;
• the inner container (2) can be disposed in the second interior (3);
• the first interior (4) is fluidically connected to a surrounding area of the system via a first opening region, the second interior (3) is fluidically connected to the surrounding area via a second opening region, the system comprises a lid (5), which can be fastened to the outer container (1) by means of a screw connection;
• when the inner container (2) is disposed in the second interior (3), the first opening region and the second opening region are covered by the lid (5) when the screw connection is established;
• the screw connection defines a virtual center axis;
• the outer container (1) comprises a cross-section tapering means, which is disposed in the second opening region and protrudes inward from the second wall;
• the cross-section tapering means is disposed in a virtual plane;
• rotation of the inner container (2) about the center axis is blocked when the collar (8) is disposed in the virtual plane;
• the inner container (2) comprises a driver element (9), which protrudes away from the collar (8) toward the cross-section tapering means when the screw connection is established.
